Along with the development of industrial technology, the yield of organic wastes is increased day by day, the organic wastes have the characteristics of large water quantity, poor biodegradability, large water quality change and the like, and the organic wastes are difficult to reduce thoroughly by the traditional treatment methods such as combustion, landfill and the like, and harmful substances such as dioxin, percolate and the like can be generated to cause secondary pollution to the environment. To date, the disposal of organic waste has become a serious threat to human sustainability.
Supercritical Water Oxidation (SCWO) is a Water treatment technology that can safely, cleanly and effectively degrade organic waste liquid with an organic matter content of less than 20 wt% at a temperature above the critical point of Water (Tc: 374.15K, Pc: 221 bar). Based on the excellent characteristics of supercritical water, a lot of organic matters and gases can be completely dissolved in the supercritical water to form a single-phase uniform mixture, thereby effectively avoiding the limitation of transmission rate between two phases and the influence of insufficient mixing. SCWO processes are capable of achieving degradation conversion efficiencies as high as 99.9%, with residence times typically in the range of seconds to minutes. Nitrogen elements in the fuel (generally referred to as organic waste) are mainly converted into N2 and a small amount of N2O, and NOx, dioxin, and the like are hardly generated.
